GAS SUPPLY

The serial plate is located inside the lower front panel. It indicates the type of gas the unit is equipped to burn. All Southbend equipment is adjusted at the factory. Check type of gas on serial plate.

These models are design-certified for operation on natural or propane gases. For natural gas, the regulator is set to deliver a 4.5" W.C. pressure to the manifold. For propane gas, it is set to deliver 11" W.C.

If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in accordance with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI

Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Installation Code CAN/CGAB149.2, as applicable.

This appliance should be connected ONLY to the type of gas for which it is equipped.

A 3/4" NPT line is provided at the rear for the gas connection. An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas required for satisfactory performance. Fluctuations of more than 25% on natural gas or 10% on propane gas will create problems and affect burner operating characteristics.

An adequate gas supply line to the unit should be no smaller than the inside diameter of the pipe from the unit to which it is connected.

Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the unit.

SPECIFICATIONS

All pipe joints and connections must be tested thoroughly for gas leaks. Use only soapy water for testing on all gases. NEVER use an open flame to check for gas leaks. All connections must be checked for leaks after the unit has been put into operation. Test pressure should not exceed 1/4" W.C.

MINIMUM CLEARANCES

! WARNING

SPECIFICATIONS

There must be adequate clearance between the left side of the ovens and combustible construction.

Minimum Clearance from Minimum Clearance from

Combustible Construction Non-Combustible Construction Back 0" 0" Right Side 0" 0" Left Side 2" 0" Floor 0" 0"

Adequate clearance must be provided in the aisle to allow the doors to open sufficiently to permit the removal of the racks and for serviceability.

Although no clearance is required behind the motor on the rear of the oven, care must be taken to provide adequate air circulation to prevent the motor from overheating.

Do not locate the oven adjacent to any high heat or grease-producing piece of equipment, such as a range top, griddle, fryer, etc., that could allow radiant heat to raise the exterior temperature of the oven above 130°F (54°C). DO NOT MOUNT ABOVE OTHER COOKING EQUIPMENT.

VENTILATION

! WARNING

Improper ventilation can result in personal injury or death. Ventilation which fails to properly remove flue products can cause headaches, drowsiness, nausea, or could result in death.

All units must be installed in such a manner that the flow of combustion and ventilation air are not obstructed. Provisions for adequate air supply must be provided. Do not obstruct the front or rear of the unit as combustion air enters through these areas.

Be sure to inspect and clean the ventilation system according to the ventilation equipment manufacturer’s instructions.

NOTICE

Proper ventilation is the owner’s responsibility. Any problem due to improper ventilation will not be covered by the warranty.

If a ventilation canopy is used, it is recommended that a canopy extend 6" past the appliance and that the bottom edge be located 6'6" from the floor. Filters should be installed at an angle of 45° or more from the horizontal. This position prevents dripping grease and facilitates collecting the run-off grease in a drip pan, unusually installed with a filter.

If an exhaust fan is used, it should be installed at least 2" above the flue opening at the top of the unit. A strong exhaust fan tends to create a vacuum in the room and may interfere with burner performance. Fresh air openings approximately equal to the fan area will relieve such a vacuum. In case of unsatisfactory performance on any appliance, check the appliance with the exhaust fan in the “OFF” position. Do this only long enough to check equipment performance. Then turn the exhaust fan back on and let it run to remove any exhaust that may have accumulated during the test.

If the oven flue is connected directly to an outside flue, a CSA International design certified down draft diverter must be installed at the flue outlet of the oven and connected to the outside flue.

INSTALLATION

NOTICE

These installation procedures must be followed by qualified personnel or warranty will be void.

The installation must conform with local codes, or in the absence of local codes, with the National

Fuel Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Installation Code CAN/CGA-B149.2, as applicable, including:

1. The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi (3.45 kPa).

Step 1: Unpacking

IMMEDIATELY INSPECT FOR SHIPPING DAMAGE

INSTALLATION

All containers should be examined for damage before and during unloading. The freight carrier has assumed responsibility for its safe transit and delivery. If damaged equipment is received, either apparent or concealed, a claim must be made with the delivering carrier.

Apparent damage or loss must be noted on the freight bill at the time of delivery. The freight bill must then be signed by the carrier representative (Driver). If the bill is not signed, the carrier may refuse the claim. The carrier can supply the necessary forms.

A request for inspection must be made to the carrier within 15 days if there is concealed damage or loss that is not apparent until after the equipment is uncrated. The carrier should arrange an inspection. Be certain to hold all contents plus all packing material.

1. Cut banding straps and remove packing material.

2. Cut banding strap holding oven to wooden skid.

3. If you are installing a single-deck SilverStar oven, go to Step 2a. If you are installing a single-deck Marathoner Gold oven, go to Step 2b. If you are installing a double-deck oven, go to Step 2c.

! WARNING

ELECTRIC GROUNDING INSTRUCTIONS

This appliance (120V ovens only) is equipped with a three-prong (grounding) plug for your protection against shock hazard and should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug.

INSTALLATION

This appliance, when installed, must be electrically grounded in accordance with local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 or the Canadian Electrical Code, CSA C22.2, as applicable.

Wiring diagrams are located on the side of the control panel assembly, as well as in this manual (beginning on page which is located inside the lower front panel.

Ovens ordered to operate on 120V power have a three-wire cord. (Double-deck ovens have two power cords, one for each oven.) Each cord has a three-prong plug that fits any standard three-prong grounded receptacle. Single-oven units require a 15 ampere supply, while double-oven units require a 20 ampere supply. (120V ovens shipped to Canada do NOT have factory installed power cords, and must be wired as described below.)

Ovens without a power cord have a terminal block. The electric supply must be brought through the service panel in the rear of the oven and connected to the terminal block. See the wiring diagrams in this manual (beginning on page

Ovens are factory-equipped with a two-pole terminal block, located behind a cover plate located on the rear of the oven. To connect the supply wires, remove the cover plate, then route the supply wires and the grounding wire through the strain relief fitting to the terminal block. Insert the supply wires, one each, into the two poles of the terminal block and tighten the screws. Insert the ground wire into the grounding lug and tighten the screw. Re-attach the cover plate.

Three phase units are wired as above, using only two supply wires. The third wire is not used and must be properly terminated.

NOTICE

45). Be sure that the input voltage and phase match the requirements shown on the serial plate,

MARATHONER GOLD & SILVERSTAR GAS CONVECTION OVENS INSTALLATION

Step 8: Connect Gas Supply

NOTICE

The installation must conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Installation Code CAN/CGA-B149.2, as applicable, including:

1. The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi (3.45 kPa).

A 3/4" NPT line is provided at the rear for the gas connection.

If this equipment is being installed at over 2,000 feet altitude and that information was not specified when ordered, contact the appropriate authorized Southbend Service Representative or the Southbend Service Department. Failure to install with proper orifice sizing will result in poor performance and may void the warranty.

The serial plate is located inside the front lower panel. It indicates the type of gas the unit is equipped to burn. All Southbend equipment is adjusted at the factory. Check type of gas on serial plate.

INSTALLATION

This appliance should be connected ONLY to the type of gas for which it is equipped. The inlet pressure before the regulator should be 7-10" W.C. for natural gas or 11-14" W.C. for LP gas.

An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas required for satisfactory performance. Fluctuations of more than 25% on natural gas or 10% on propane gas will create problems and affect burner operating characteristics.

An adequate gas supply line to the unit should be no smaller than the I.D. of the pipe from the unit to which it is connected.

Purge the supply line to clean out dust, dirt, or other foreign matter

before

connecting the line to the unit.

! CAUTION

ALL PIPE JOINTS AND CONNECTIONS MUST BE TESTED THOROUGHLY FOR GAS LEAKS. USE ONLY SOAPY WATER FOR TESTING ON ALL GASES. NEVER USE AN OPEN FLAME TO CHECK FOR GAS LEAKS. ALL CONNECTIONS MUST BE CHECKED FOR LEAKS AFTER THE UNIT HAS BEEN PUT INTO OPERATION. TEST PRESSURE SHOULD NOT EXCEED 1/4" W.C.

Step 9: Check the Installation

1. Check that all screws and bolts are tightened.

2. Move the oven into the position at which it will be operated.

3. Check that the oven is level. If not, adjust the legs.

4. Check that the appropriate clearances are satisfied (see page 8).

OPERATION MARATHONER GOLD & SILVERSTAR GAS CONVECTION OVENS

OPERATION

! DANGER

EXPLOSION HAZARD

In the event a gas odor is detected, shut down equipment at the main shut off valve. Immediately call the emergency phone number of your gas supplier.

! CAUTION

To eliminate gas build up which could result in an explosion, in the event of main burner ignition failure a five minute purge period must be observed prior to re-establishing ignition source.

OPERATION

For an appliance equipped with a convection oven, no attempt should be made to operate oven during a power failure.

LIGHTING, RELIGHTING, AND SHUTDOWN INSTRUCTIONS

To light the oven, just switch the power switch at the top left corner of the control panel to the “ON” position. (The oven is equipped with a direct hot surface ignition system. There is no pilot to light.)

If the burners fail to ignite within four seconds, the oven will automatically shut off the gas, wait five minutes to allow the gas that was released to dissipate, and try to light the burners again. If the burners still fail to ignite after three such attempts, the oven will stop trying, even though the power switch is in the “ON” position. To continue to attempt to light the burners, turn the power switch “OFF” and then “ON” again.

To shutdown the oven, switch the power switch to the “OFF” position. For a complete shutdown, also open the control panel and turn the manual shut-off valve to the “OFF” position.

OPERATING THE CONTROLS

A convection oven is a different type of oven that offers many features and advantages to the food service operation. The additional capabilities and features of the oven require some learning. However, the operation of the oven is not difficult to understand or control once you have some practice.

The oven will have one of the four types of control panels:

• Models with Standard Controls are the most similar to a standard (non-convection) oven. Instructions for operating this type of oven begin on page

NOTICE

23.

• Models with Cycle/Cook and Hold Controls enable you to have the oven automatically enter a “hold mode” after a timed cooking period. Instructions for operating this type of oven begin on page

• Models with Programmable Controls enable you to have the oven change temperature and other settings while cooking, then optionally enter a “hold mode.” You can record up to five “cook programs” which can then be re-used later. Instructions for operating this type of oven begin on page

• Models with Rack Timer Controls provide five separate timers that independently time the cooking of food on each rack of the oven. The oven will tell you which rack will finish cooking next, and how much time remains. Instructions for operating this type of oven begin on page
